Summary: I have used a wide variety of inexpensive Koss headphones, and these offer the best combination of comfort and loud sound. The sound is what you'd expect from an on-ear headphone, but not as interesting as the titanium tweeters of the KSC75.
Summary: I have particularly small ears. I cannot wear the "ear buds" because they ALWAYS fall out! These are great!! The over-the ear part is pliable wire, so I could mold them so they fit perfectly on my small ears. I LOVE THEM! No more falling out every time you talk or turn your head!!
